logic al connection between two activities. [D01620] WST logic al or natural association between two or more things; relevance of one to another; connection. [D01621] VPM 19 A semantic connection among model element s. Examples of relationships include association s and generalization [D04874] RUP

A reference or link between one object and one or more other objects. Relationships may be one-to-one, one-to-many, many-to-one, or many-to-many. They may connect objects of the same class or different classes. In Objectivity/DB, relationships are persistent objects that are stored in the database.

(1) An interaction between entities. Usually expressed as verbs in English. (2) A named business association between occurrences of one or more entity types which provides some relevant information value.

A logical link between two tables that describes how the tables are associated with each other One-To-Many: A relationship in which one record in a table can related to any number of records in another table. (A teacher may have many students, an order may have many items, a department may have many employees etc.) One-To-One: A relationship in which one record in a table relates to only one record in another table. (A patient table, detailing address and billing information may relate to one record in the Patients' Personal table, detailing health information, treatments etc.) Many -To-Many: A relationship where any number of records in a table can relate to any number of records in another table. An example might be the relationships between people and addresses, in which many people can have the same address AND any one person may have a number of addresses (home, work, townhouse etc.). This type of relationship is implemented by creating a new 'join table' and creating two one-to-many relationships from the original tables to the third table. The 'join table' would include two foreign keys - one to each of the other two tables' primary keys.

Describes the dependency or connectivity between CIs using terms such as 'used by', 'part of', 'connected to', 'resides on'. Relationships not only provide a means of assessing the potential full impact of a proposed Change, but can also indicate the potential damage likely to be caused by a single component failure. Relationships are described as 'primary' if they are hierarchical and 'secondary' if not.

A link between tables that references the primary key in one table to a foreign key in another table. The relationship line is represented in a database diagram by a solid line if referential integrity between tables is enforced, or a dashed line if referential integrity is not enforced for INSERT and UPDATE transactions. The endpoints of a relationship line show a primary key symbol to denote a primary key-to-foreign key relationship or an infinity symbol to denote the foreign key side of a one-to-many relationship.

An association, linkage, or connection, either real or suspected, between entities of the same or different set which describes their interaction, the dependence of one upon the other, or their mutual interdependence.

Conceptual connection between two or more entities in entity-relationship modelling. Relationships may be one-to-one, one-to-many or many-to-many. Eventually, a static connection between two or more objects, that is commonly implemented using pointer reference.

A statement about how two or more entities are related and the restrictions placed on that relationship. Example, a Department employs zero, one or many Employees and an Employee can work for one And only one Department (italics identify the relationship between Department and Employee).

This defines a geometrical connection between two entities that is enforced by the program. For example, if you fix a point to a curve, then you can only move or drag the point along that curve. Likewise, if you move the curve, the point will remain attached to the curve and remain in the same relative position.

A type of connection or business association of interest or meaning that can exist between two entity types. Identifies the business reason (rule) within the Ministry why two or more entity types may be associated.

This is a logical connection between two classes. There are two basic kinds of relationships: associations and subclassing relations. Unfortunately the word is often used synonymously with association. (See the category on relationships.)

A link between two entities that's based on attributes of the entities. For example, the Department and Employee entities can have a relationship based on the deptID attribute as a foreign key in Employee, and as the primary key in Department note that although the join attribute deptID is the same for the source and destination entities in this example, it doesn't have to be. This relationship would make it possible to find the employees for a given department.

A relationship is a connection of some kind between two things. Typical forms of relationship are interpersonal relationships between two people, cause-effect relationships between two events, mathematical relations and systemic relationships between two parts of a system.

defined in terms of genealogy--common ancestral species. Two species are more closely related to one another than to a third species if they share a more recent common ancestor that either does with the third. These two taxa are considered as sister groups.

The relationship of a person to a business is either administrator or employee, depending on how the person registered. A Business Registration results in an administrator relationship. An Employee Registration results in an employee relationship. The relationship of a business to HFS is documented by an HFS Identification Number, dependent on business type.

A relation between people; ("relationship" is often used where "relation" would serve, as in "the relationship between inflation and unemployment", but the preferred usage of "relationship" is for human relations or states of relatedness); "the relationship between mothers and their children".

An archaeological relationship is the position in space and by implication, in time, of an object or context with respect to another. This is determined, not by linear measurement but by determining the sequence of their deposition - which arrived before the other. The key to this is stratigraphy.

a knitted or crocheted fabric, not a cotton ball (well actually after a while it is like a cotton ball too because in a cotton ball is a tangle of individualized fibers that seem to stick together organically)

Relationships are used to define views This can include parent-child relationships, as well as weaker many-to-many relationships. Relationships use attributes to create filters based on contextual information. For instance, to find equipment at the user's default location, or job plans for the selected work order.
